Abstract

An endoscopic tissue anchor deployment device includes a handle, an elongated shaft defining an internal lumen, and an end effector attached to the distal end of the elongated shaft. A tissue anchor catheter is removably inserted through the lumen of the elongated shaft, the catheter having a tissue anchor assembly that is deployable from its distal end. In some embodiments, the handle includes a pin and track assembly that define a series of handle actuation steps corresponding to deployment steps for the deployment device end effector and the tissue anchor catheter. In some embodiments, the handle includes a catheter stop member that prevents movement of the tissue anchor catheter under certain circumstances, and a handle stop member that prevents actuation of the handle under certain circumstances.
